You'll be able to buy it even less when you hear this: The reason it's not backed up in the places you say is that dead Athena Liu wrote on an old Remington typewriter.

The plot is so contrived: It would never have "worked" (to the degree that it does at all) had Athena been a normal 27-year-old who wrote on a computer.

Thanks for alerting me to the "Say, you haven't shown this to anyone, have you?" trope. I can't recall having seen it. But now that you've mentioned the device, I bet I'll be seeing it around every literary corner :).
